, MOVING-PICTURE-OPERATORS AUTOMATIC SIGNALING DEVICE.

' ,1; To all whom it may concern:

, Be it known that I, OSCAR B. DAY, a citizen ofthe United States, residing at Greencastle, in the county of Putnam and State of Indiana, have-invented a new and useful Moving Picture Operators Automatic he present invention appertains to improvements in moving picture operators automatic signaling devices.

An object of the invention is to provide picture operators automatic slgnaling evice so shaped or designed as to admit of its easy attachment within the ma azi'ne.

other object of the invention is to provide a movin picture operators automatic si aling device that obviates the necessity o punching holes through, or otherwise mutilating the fihn as at present done, as a warning to the operator to change machines.

Still another object of the invention is to provide a moving picture operators automatic signalingdevice that, is simple 1n construction and dependable in operation, and t e expense of which is not an obstacle to its use.

With the above and other objects in view, that will appear as the description proceeds, the invention resides in the combination and parts and in the details of constructiondescribed and claimed, it being understood that changes in the precise embodiment of the invention can be made within the scope of what is claimed without departin from its spirit as hereinafter describe claimed and illustrated in the ac companyin'g drawings in which Figure 1 is a plan View picture operators automatic signaling device, the rollers cut through the center longitudinally showing the various parts as hereinafter described, and also showing the connectionwith the battery and signal bell.

Fig. 2 is a sectional view of the moving picture operators automatic signaling device showing a cross section of the frame 1.

ing device, showing the device, the film, a portlon of a magazine, a portion of a reel and also showin the film passing between the rollers and through the slot at the bothe magazine,

the magazine, reel, slot being as at present used, and

shown to more clearly illustrate the inven to the accompanying characters throughout denotes in general my improved movin picture operators automatic signaling device which consists preferably of a frame 1, which consists of a metal plate having one portion bent at right angles to the other and having lugs 19, as shown, at each end thereof. Contact rollers 2 are secured to the frame 1 on which the contact rollers spindles 3 are internally end at 4 for the reception 2 rotate; the threaded at one of the screws 10, the spindles 3 passing The contact rollers 2 are provided with shoulders 11, with which the perforated edges of the film 26 are in contact as it passes through the automatic signaling device, the purpose'of which will be later explained. The contact rollers 2 are provided with flanges 12 for the purpose of retaining the film 26 in its proper position on the rollers 2.

A tension roller 13 having shoulders 16 at each end thereof is provided, as shown, the roller 13 being secured to the frame 1 by a spindle 14 which is internally threaded at one end for the reception of a screw 10, and having a head 15 at the opposite end.

Washers 20 through which the screws 10 pass are provided for the rollers 2 and 13.

uide rollers 17 having shoulders 18 are secured to the frame 1 by the lugs 19, the

by spindles 3,

I end, and

i the film 26 against contact with t film 26 containing purphse of the guide rollers beinglto protect e frame 1.

The shoulders with which-the various rollers are describe form the grooves 21, the purpose of which is to prevent the portion of the the pictures coming in thus preventing the as the film 26 passes device. with oil The automatic signaling device is connect-.

ed with the battery and bell by means of the cords 22, 23 and 24 as shown in Fig. 1. he device is threaded by placing the film 26 back of the contact rollers 2, in front of the tension roller 13 and between the contact roller 2 and the guide rollers 17, as shown.

The operation of the automatic signaling device is as follows: When one of the strips 27 is brought into contact with both of the rollers 2, by the movement of the film 26 through the device, the circuit is completed and the signal given by the ringing of the bell which continues until the circuit is broken by the strip 27 being in contact with only one of the rollers 2.

From the foregoing disclosures it will be manifest that a-moving'picture operators automatic signalin device is provided, which will fulfil al quirements of such a device.

What I claim as new and desire to secure icy Letters Patent is 2- LA moving picture operators automatic signaling device including a frame to which contact rollers having shoulders and flanges at'each end thereof are attached; spindles by which the contact rollers are attached to the frame and on which the contact rollers rotate, the spindles passing through nonconducting washers placed between the ends of the rollers and frame,

through non-conducting collars placed in holes in the frame, through nonconducting washers outside of the frame and throu h the eyes to which the cords are attached, the spindles being provided with nuts at one washers and screws at the other, as specified and shown.

2. A moving picture operators automatic signaling device including a frame to which contact rollers, having shoulders and flanges at each end thereof are attached; spindles rovided, as shown and previously havin tai'ning the contact rollers and 'sp in parallel spaced relation with of the necessary reby which the the frame and on which the contact rollers rotate, the spindles passing through nonconductin washers laced between the ends of the rol ers and ramethrough nonconducting collars placed in holes in the frame, and through nonconducting washers outside the frame, and through the eyes to which the cords are attached, the spindles being provided with nuts at one end and washers and screws at the other; a tension roller a shoulder at each end; a spindle by which the tension roller is attached to the frame, between the contact rollers and on which the tension roller rotates, the spindle having a head at one end and being rocontact rollers are attached to 65 vided with a washer and screw at the ot er,

as shown and described.

3. A moving picture operators automatic signaling device including a frame to which contact rollers are attached; spindles by which the contact rollers are attached to the frame and on which the contact rollers rotate; means for insulating the spindles and contact rollers from the frame; means for attaching the eyes to which the cords are secured to the spindles; means for reindles in their required positions; a tension roller having a shoulder at each end; a spindle by which the tension roller is' attached to the frame, and on which the tension roller rotates and means for retaining the tension roller and spindle in their required positions; a pair of-guide rollers havin shoulders and pivots at each end thereo one of which is attached at each end of the frame by means of lugs, the various rollers being each other specified and shown.

4. A moving picture operators automatic signaling device including a frame to which contact rollers are attached; spindles by which the contact rollers are attached to the frame and on which the. rollers rotate, the contact rollers being provided with shoulders and flanges at each end, the spindles and rollers being insulated from the frame by nonconducting washers and collars; means for securing the eyes to which the cords are attached to the spindles; means for retaining the contact rollers and spindles in their required positions; a tension roller having a shoulder at each end; a spindle by which the tension roller is attached to the frame and on which the tension roller rotates, and means for retaining the tension roller and spindle in their required positions; a pair of guide rollers having shoulders and pivots at each end, one of which is attached at each end of the frame by means of lugs; grooves in the various rollers formed by the shoulders thereon; the several rollers in parallel spaced relation with each other; a film to which strips of and described and for the purpose speci- 10 tinfoil, or other suitable conducting matefied.-

rial, are attached, near an edge of the film, In testimony that I claim the foregoing one of the strips of tinfoil being attached at. as my own, I have hereto affixed my signathe end and the other at a distance from the ture in the presence of two witnesses.
